Real Madrid’s Cristiano Ronaldo celebrates after scoring their second goal against Barcelona in this file photo.

Manchester United vs Real Madrid takes place in the Champions League on Wednesday night, in what promises to be the tie of the round. This match will draw millions of soccer fans around the world, and features a host of the world's best players. The game kicks off at 7.45 p.m. UK time and can be watched online through free live stream (details below).

This match reignites the rivalry between United's Sir Alex Ferguson and Real's Jose Mourinho, in one of the great managerial match ups. The pair had a fierce rivalry in the English Premier League when Mourinho was in charge of Chelsea, and many are looking at this tie with huge anticipation in what should be a fantastic match.

The match will also pit one of the world's best players, Cristiano Ronaldo, against his former team. Ronaldo was arguably United's best player when he played for them before joining Real, but since joining the reigning Spanish La Liga champions he has been in phenomenal form, scoring at roughly a goal per game. It will take an immense effort from United's players to contain him, and it should be an intense and intriguing reunion.

For United, veteran midfielder Paul Scholes will miss this first leg tie, as he is out with a knee injury. He has not played since January's 4-1 win against Fulham in the 3rd round of the FA Cup, and he will be sorely missed by the United team.

Rio Ferdinand and Michael Carrick, however, are expected to be recalled.

Real have had the luxury of resting a number of players for this game including midfielders Xabi Alonso, Mesut Ozil and Sami Khedira. However, Diego Lopez is expected to continue in goal after regular keeper, Iker Casillas, suffered a broken hand recently.
